Just for future reference: this version does not exist in git, so it
doesn't tell me much. What does M-x org-version say? That's the
important thing (of course, the Archlinux people might have modified it

Be that as it may, I checked that release_7.7 had the problem, so I tried
a bisection and found that the fix is in the following commit:

|     org-footnote: prevent LaTeX export from catching footnotes in protect environment
|     
|     * lisp/org-footnote.el (org-footnote-in-valid-context-p): check
|       `org-protected' property before allowing to match a footnote.
|     (org-footnote-at-reference-p): remove an obsolete test. It's now done
|     in the previous function.
